Could you be at higher risk?
The 7 most common risk factors for nighttime dry eye
Risk factor 1 / 7
LASIK or PRK
Refractive surgery can reduce corneal sensation and tear production, leaving eyes vulnerable at night.
Risk factor 2 / 7
Perimenopause & Menopause
Hormonal shifts reduce tear quality, making nighttime dryness a common surprise.
Risk factor 3 / 7
Dry Eye / MGD
Tear-film instability worsens during sleep — when blinking stops and exposure rises.
Risk factor 4 / 7
Sleep Apnea & CPAP
Air leaks from masks dry out the eye surface all night long.
Risk factor 5 / 7
Thyroid Eye Disease
Bulging or retracted eyelids prevent a full overnight close.
Risk factor 6 / 7
Bell's Palsy / Stroke
Facial weakness can leave one eye partially open while you sleep.
Risk factor 7 / 7
Eyelid Surgery
Blepharoplasty can subtly change how completely your lids meet at night.
Tape works- until it hurts.
It sticks. It pulls. It irritates.
Hydrogel is mostly water--so it's gentle and soothing.
Hypoallergenic
Medical-grade hydrogel that won't irritate delicate eyelid skin.
Highest water content
More moisture, less adhesive — so it soothes, protects, and peels off painlessly.
Patented seal
Stays in place all night, with no residue and no lash damage.
